I am using the Windows Binary of Version 4.31, and an external email utility
that sends SMTP outgoing email.
I can configure for specific ports (no problem). and I can send SSMTP
SSLv3 with success. That is GOOD !
I am trying to configure Stunnel for sending TLSv1 without success.
I understand (via the Version command and screen) that Stunnel defaults to
SSLv3.
How do I change that to TLSv1 ??
I found the parameter :
sslVersion = version
select version of SSL protocol
Allowed options: all, SSLv2, SSLv3, TLSv1
This appears to be a "SERVICE LEVEL" option, and I have tried to use the
line:
sslVersion = TLSv1
in the [SSMTP] group of options (along with accept = and connect = ), but
get an error message in the log file, which is shown next:
2010.02.25 10:35:44 LOG3[2696:2740]: SSL_connect: 1408F10B:
error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
I have also tried to put the sslVersion = line in the general
configuration area, but generate the same error message.
The outbound email does, in fact, fail.
Can anyone suggest what I am doing wrong ?? Or offer a solution for
configuring Stunnel (V4.31) for TLSv1 ??
